2 Claims. (Cl. 73-100) Our invention resides in the provision of novelmeans for subjecting a hogshead panel topressures similar to those itwill receive in use in order to eliminate defective panels fromhogsheads.

It is an important object of our invention to provide a testing devicewhich will simulate actual conditions to which the panel will besubjected when incorporated in a hogshead.

Another object of our invention is to provide a testing device having awide range of pressures which may be applied against the particularhogshead panel as desired.

A further object of our invention is to provide a testing device havingmeans for clamping a hogshead panel thereon so as to enable the safe useof high pressures in rality of hogshead panels. are joined by hoops 11and hoops and liners 12. Later they will be sawed along the dotted lines13 in order to form a plurality of slats;

In order to secure accurate results in testing a questionable panel itis important that it be subjected to conditions which closely simulatethose to which it will be subjected if included as one of the panelsmaking up a hogshead. With that in mind we have constructed our testingdevice as follows. As perhaps best seen in Figures 3 and 4 the devicecomprises a table 14 mounted on legs 15 and having a suitablebed member16. The bed order to locate whatever defects there might be in thepanel.

These and other objects of our invention will become apparent to thoseskilled in the art during the course of the following description andwith reference to the accompanying drawings, in which drawings likenumerals are employed to designate like parts and in which:

Figure l is a plan view of a typical hogshead panel which will be testedby the device of this invention,

Figure 2 is a plan view of an assembly of hogshead panels such as shownin Figure 1,

Figure 3 is a plan view, with parts broken away, of the testing deviceof this invention,

Figure 4 is a section taken on the line 4-4 of Figure 3,

Figure 5 is an enlarged fragmentary sectional view showing in detail thelatch mechanism for securing the panel in place,

Figure 6 is an enlarged perspective view showing detail of the structureof Figure 5 and Figure 7 is an enlarged perspective view showing furtherdetail of the arrangement of Figure 5.

In manufacturing hogsheads we have found it desirable to employ panelsmade of plywood and the like. These panels may be assembled together inside-by-side relationship and bound by a plurality of metal straps.Following this the assembly of panels may be sawed so as to form whatamounts to a plurality of slats. The sawed assembly of joined panels maythen be shaped to form a hogshead after which tops and bottoms may beapplied. These hogsheads are subjected to considerable pressure whenthey are loaded and they often are given rather rough treatment whenhandled in warehouses and during transportation. Accordingly it isimportant that the panels from which the hogsheads are formed are ofgood quality.

In Figure l we have shown a typical hogshead panel as indicated at 10.Workmen having a supply of these panels available will take them andplace several in side-by-side relationship in order to rough out ahogshead. Three such panels have been indicated at 10a, 10b and 100 inFigure 2. Ordinarily these workmen will inspect the panel as it is putinto position. If there is any doubt about the quality of the panel andits strength it is set aside for testing as will be described. Theplumember 16 has upstanding sides and ends which are grooved at 17 toreceive a panel member 10.. These sides and ends 18 and 19 maintain thepanel 10 sufiiciently spaced from the bottom of the member 16 as toprovide room for the pressure envelope 20. V

The panel 16 is maintained in position on the bed member 116 by aframework which is pivotally mounted on a shaft 21. This shaft 21 ismountedin suitable bearings 22 based on the table 14. The frameworkcomprises the members 23 which will engage the ends of the panel 10 soas to correspond in position to the hoop and liners 12. The frameworkalso includes a pair of members 24 which will engage the panel 10 in aposition corresponding to that which will be taken by the hoops 11 ifthe panel ii) is included in a hogshead. The members 23 and 24 are fixedto the shaft 21. A pair of brace members 25 extend across the members 23and 24 and may be welded or otherwise secured thereto. Members 26 arefixed to the brace members 25 and arranged to form the handle 27.

From the foregoing description it will be apparent that by grasping thehandle 27 the frame structure including the members 23 and 24 may bemoved from the full line position of Figure 4 to the dotted lineposition thereof. In this dotted line or out-of-the-way position theframe structure may rest against the stop 28 fixed on the lugs 29extending from the bed 14. When a panel 10 has been placed in thegrooves 17 provided in the tops of the sides and ends 18 and 19 of thebed member 16 the frame structure is then brought to the full-lineposition of Figure 4 where it will be observed that the members 23 lieacross the ends of the panel while the members 24 engage the panelcentrally thereof. Means are provided to clamp this frame assembly inposition above the panel member 10.

A shaft 30 is mounted in a plurality of bearings 31 extending from thetable 14. A handle 32 by means of which the shaft 30 may be rotated inits bearings is also fixed to the shaft. Latch means for the ends ofeach of the members 23 and 24 are mounted on this shaft 30. It will beunderstood that each of these four latch means is alike and therefore weshall describe only one.

As perhaps best seen in Figures 4 and 5 the latch means comprises ashort link 33 which is pinned to the shaft 36 as indicated at 34. Thelatch member 35 is pinned to the end of the short link 33 as indicatedat 36. The latch member 35 has a face 37 adapted to engage the end ofthe members 23 and 24 in the area indicated at 38. The latch member 35may be bifurcated so as to provide portions 39 and 40 which straddle theshort link 33 as best seen in Figure 7.

When a panel has been placed on the table member 16 and the framestructure including the members 23 and 24 have been engaged with thispanel the various latch members 35' are then engaged about the ends 38of the members 23 and 24. After each of the latch members 35 has beenput in place the handle 32 is then moved in a clockwise direction asviewed in Figures 4 .and 5. This will rotate the shaft 30 and link 33 soas .to move the pin 36 out of vertical alignment with the shaft 30thereby insuring that the latch members 35 will be-locked in place. Thispast center arrangement prevents accidental displacement of the latchmembers.

The pressure envelope 20 is preferable made of a strong, flexiblematerial capablei of withstanding high pressures. -A" fitting dlconnects this envelope m with a suitable conduit extending from a'sourceof air under pressure. Loeatedin the conduit 42'is'a regulator valve 43,anofi and on valve 44' and agauge 4S. When air under pressure isadmitedwithin theenvelope 29 h will expand uniformly 'and conta'ct theunderside of the panel and urge this panel tightly against the framemembers 23 and 24 which'are now locked in position'by the latches 35 asdescribed. "ln'thismiannerthe panel 10 may be subjected to whateverpressure is desired. The panel may be inspectedt'o see whether anydefeets did occur as 'a result of the high pressure applied;

By locating the'memberslland 24 in positions correspending to thoseabout which the hoops and hoops and liners 11 and 12 will be disposed ifthe panel is used in forming' a hogshead, and by providing the flexibleenvelope 20 whereby pressure is applied evenly throughciut the panel, weare able to closely approximate the conditions to whicha hogshead panelis subjected when inusel ln'this manner we can get accurate informationits to whether'a questionable panel should be used or not.

i It is believed that the operation of'this device has been fully setforth above and that it is easily understood by those skilled in theart. To describe it further at this point would seem repetitious.

It will be apparent to those skilled in the art that certainmodificationsmay be made in the device of this invention withoutdeparting from the scope and spirit thereof. it should beunderstood'that while we have shown our invention as embodied in certainparticular structures and arrangements We' do not intend to be 4 limitedto such structures except insofar as they are specifically set forth inthe subjoined claims. 1
